S-100 power supply voltage ranges

All of the S100 boards I've seen use simple linear regulators, so you 

need some headroom--but not too much.  A lot of S100 7805s and LM323-
5s were operated within an inch of their maximum current ratings 
(some had bypass resistors installed) and generated a lot of heat.  I 

wouldn't run the supply rails any higher than I had to.

Cheers,
Chuck
